Whether Extreme Unction avails for the remission of sins?

Objections

Objection 1 : It would seem that Extreme Unction does not avail for the remission of sins. For when a thing can be attained by one means, no other is needed. Now repentance is required in the recipient of Extreme Unction for the remission of his sins. Therefore sins are not remitted by Extreme Unction.
Objection 2 : Further, there are no more than three things in sin, the stain, the debt of punishment, and the remnants of sin. Now Extreme Unction does not remit the stain without contrition, and this remits sin even without Unction; nor does it remit the punishment, for if the recipient recover, he is still bound to fulfill the satisfaction enjoined; nor does it take away the remnants of sin, since the dispositions remaining from preceding acts still remain, as may easily be seen after recovery. Therefore remission of sins is by no means the effect of Extreme Unction.
Objection 3 : Further, remission of sins takes place, not successively, but instantaneously. On the other hand, Extreme Unction is not done all at once, since several anointings are required. Therefore the remission of sins is not its effect.
